“Most receive their markings in the main hall, but I wanted you to receive yours in the presence of Yangchen, the last Air Nomad to be the Avatar. When she died, the next Avatar was born into the following nation in the eternal cycle, so after Yangchen's death came Kuruk of the Water Tribes, then Kyoshi of the Earth Kingdom. And then Roku in the Fire Nation, which means the next Avatar will once again be an Airbender.”
―Gyatso explains Yangchen and the Avatar cycle to Aang
